ing drawings, forming part of this specification.

The object of my invention is to provide a construction of metal frame for window screens which shall be rigid, durable, readily and easily put together, and in which the means provided for locking and holding the wire screening shall bev so arranged that the wire screen can be easily released and the screen rewired in the field, should the original screening become damaged or destroyed A further object relates to the arrangement of amore effective construction for holding the screen in the Window guides, by which the narrow flat springs heretofore employed are dispensed with.

A further object is to provide for the ready and easy attachment of the finger lifts to the molding without interfering with the removal and replacement of the screening.

The several features of my invention and the various advantages resulting from their use conjointly or otherwise will be apparent from the following description and claims.

In the drawings, Figure 1 is a plan view of one corner of my improved screen. Fig. 2 is a transverse section, in perspective; of a portion of the top and bottom molding showing the method of locking the wire screening. Fig. 3 is a perspective view of one end of the molding for the sides of the frame, with the screening removed. Fig. 4

' is a longitudinal section of one corner of the frame showing the method of securing the springs. Fig. 5 is a front elevation of the same. Fig. 6 is a front elevation of a portion of the frame illustrating the finger lift. Fig. 7 is a transverse section of the same. Fig. 8 is a section of the frame molding and guide rail for one side of the win dow frame, and Fig. 9 is a section of the opposite guide rail,these two views illustrating the differences in height of the two rails. Fig! 10 is a perspective View of the corner pieces.

My improved framework or molding for the .window screen is formed in suitable dies, preferably from an integral strip of sheet metal for each of the four sides of the frame. The strip is for one longitudinal edge curved and. bent over on itself to form a substantial semi cylindrical portion made up of the semi-cylindrical walls 1 and 2. The strip of sheet metal is also bent to form the flat front face 3 of the moldin and for the two sides of the molding flame the metal sheet is bent inwardly to form the bottom 4 and the two side walls 5, 6, of a groove which isadapted to ride on the vertical guide rail in the window frame. The metal strip is then bent to form the opposite side of the molding frame'7, substantially parallel with the wall 3, and the strip 'is then bent inwardly to form an oblique portion 8, and the edge turned over to form a flange and preferably curved into a slight are 9. This construction of the molding with the grooves is provided for the sides of the screen frame, and for the bottom and top the construction is the same, except that a flat bottom 10 is formed instead of a groove. With this construction, the curved portion 1, 2, especially with the lower edge of the strip 12 locked around-the base of the curve, forms a rigid and substantial seat for the rod 13. The oblique member 8 of the molding with the side portion 9 forms a resilient member and a holding edge for the rod.

The wire screening 35 having been cut of the desired size, is laid within the segmental i seat formed by the walls 1 and 2, and the construction for holding the wire, while at the same time whenever it is desired to replace the wire screening, the molding may be. sprung so as to release the rods, new screening can be inserted and the rods replaced without difficulty.

The sides and bottom and top pieces making up the window screen frame are beveled at the corners to fit together, as shown at 14, and in order to lock and hold together the corners and at -the same time provide a spring construction for holding the window screen on the guide rails in the window and to permit the screen to be removed and replaced, I provide as follows: A sheet metal box is formed of ,the sides 15, 15, with right angled extensions 17, 18, and with a connecting base 19, as shown in Fig. 10. The end wall 20 is formed preferably by turning over the ends of thewalls 15, 16, with a cir cular opening 21 in the end wall, in which is mounted the rod 22, preferably 'provided with a head 23. A =C01ld spring 24 (Fig. 4) is mounted between the end wall 20 and the head 23, the tendency of which is to project outwardly the rod or bolt 22. The boxing is pushed into the top and bottom portions of the molding. The sides 15, 16 are preferably made to conform to the heights of the walls 3 and 7, and the width of the box is such as to fit snugly in the molding;

The right angled plates 17 18 are then passed mto the grooves formed by the walls 3 and 5, and 6 and 7 of the grooved members of the molding. These parts of the boxing fit snugly into the respective members of the molding frame, and the members of the frame are held rigidly and securely at the corners by sweating or brazing after the parts have been inserted. ,,.A rectangular loop of sheet metal, with a long arm 25 and a short arm 26 and a connecting base 27, is slipped over the head of the bolt 22, with the short arm formed with a slight hook 28 to engage under the edge of the'base 4 of the groove, and with the longer member 25 prlll shed in alongthe bottom 19 of the boxing.

this way, a smooth bearing surface 27 1s provided for engagement with the guide rails forthe screen. These ide rails are preferably hollow rails 29 30, vertically secured by screws 31, 31, to the pulley stile, andone of the rails is approximately twice the height of the other.

The spring bolts, it will be understood, are only provided for one side of the frame at top and bottom. For the other corners, the same angle pieces are employed for securing and bracing the corners, but the bolts and springs are omitted, because it is only necessary to have the spring construction on oneside. Thesprings are employed for the side, arran ed to engage the rail 29, while for the rai 30' no spring devices are emplo ed.

, n order to locate the screen in position in the window, the screen is inserted b compressing. the springs until the opposite side In the ordinary constructions a flat s ringis used at the base of the groove, an this flat spring must either. besufiiciently powerful so that it is difficult to compress the same, or considerable space must be given up to. the springs. With my improved construction as above outlined, the springs themselves are located in the hollow portion of the molding of the top and bottom portions so that ample space is provided for, and coiled springs can be used, which are much more uniform and effective in their operation than flat springs.

My construction of molding also lends itself to ready and easy'attachment of the lifts for raisin the screen. A plate 36 is provided, whic is curved to fit around the semi-circular wall- 2. This plate is formed with an upwardly projecting loop 37 which is raised at its middle portion at 38,, and the opposite edge of the plate is folded back under the folded-over edge of the molding walls 1, 2, at 39. The edge of the walls 1, 2, is raised slightly where clasped by the lift holding plate, so that a smooth seat is left for the locking rods 13, without any interference from the attachment. The finger loop 40 is then inserted, with its inner ends engaged by the loop 37, and with the inner ends bent upwardly slightly, as indicated at 41 in Fig. 6, so that these ends will come within the raised portion 38 of the holding plate. With this construction, the finger loops 40 will be held in upright position out of the way in close contact with the'wire mesh. They can easily be turned outwardly forv the insertion of the fingers for raising the screen, and as soon as the fin er loops are released, they are returned to t eir normal upright position, by reason of the fact that in turning the loops on the pivotal portion of the plate, the ends of the finger loops are brought in contact with the ,contracted narrower portion of the plate walls, so that there is sufiicient resiliency to-bring the finger loops back to their upright position as a screening, one edge formed into a seat seg formed from an integral strip of sheet metal, bent into hollow shape with its longitudinal sideledges projecting toward the.

mental in cross. section, and the other edge bent obliquely towardthe opposing seat to form a resilient locking member, with a rod between which and .the segmental seat the wire screening is engaged, and the rod locked in ositionby the resilient member of the mol ing. 7
